Outside/In

A podcast in which curiosity and the natural world collide. Outside /n is hosted by Nate Hegyi, and is a production of New Hampshire Public Radio.

  • A scholar and an activist make an uncompromising ultimatum. A forgotten burial ground is discovered under the streets of New York City. In Philadelphia, two groups fight over the definition of “descendant community.” Featuring Michael Blakey, Lyra Monteiro, Chris Woods, aAliy Muhammad, Wendell Mapson, Sacharja Cunningham, Jazmin Benton, Amrah Salomon, and Aja Lans. MORE ABOUT “WHAT REMAINS”Across the country, the remains of tens of thousands of human beings are held by museums and institutions. Scientists say they’ve helped lay the foundations of forensic science and unlocked the secrets of humanity’s shared past. But these bones were also collected before informed consent was the gold standard for ethical study. 19th and 20th-century physicians and anthropologists took unclaimed bodies from poorhouses and hospitals, robbed graves, and looted Indigenous bones from sacred sites.Now, under pressure from activists and an evolving scientific community, these institutions are rethinking what to do with their unethically collected human remains. Outside/In producer Felix Poon has informally gained a reputation as the podcast’s “death beat” correspondent. He’s visited a human decomposition facility (aka, “body farm”), reported on the growing trend of “green burial,” and explored the use of psychedelic mushrooms to help terminal cancer patients confront death.In this three-episode series from Outside/In, Felix takes us to Philadelphia, where the prestigious Penn Museum has promised to “respectfully repatriate” hundreds of skulls collected by 19th century physician Samuel George Morton, who used them to pursue pseudo-scientific theories of white supremacy. Those efforts have been met with support by some, and anger and distrust by others. Along the way, Felix explores the long legacy of scientific racism, lingering questions over the 1985 MOVE bombing, and evolving ethics in the field of biological anthropology.Can the institutions that have long benefited from these remains be trusted to give them up? And if so, who decides what happens next?

  • When KALW’s Marissa Ortega-Welch hit the Pacific Crest Trail, she used her preferred method of navigation: an old-fashioned trail map. But along the way, she met a couple who only used phones to guide them, a Search and Rescue team that welcomes the power of GPS, and a woman who has been told her adaptive wheelchair isn't allowed in official wilderness areas (not actually true).So… does technology help people access wilderness? Or does it get in the way? This week’s episode comes to us from “How Wild” produced by our friends at KALW Public Media. In this seven-part series, host Marissa Ortega-Welch charts the complex meaning of “wilderness” in the United States and how it’s changing. Marissa criss-crosses the country to speak with hikers, land managers, scientists and Indigenous leaders – people who spend every day grappling with how ideas about wilderness play out in the hundreds of designated wilderness areas across the U.S. LINKSCheck out more episodes of “How Wild” here.SUPPORTOutside/In is made possible with listener support.

  • In the early 1900s, people didn’t trust refrigerated food. Fruits and vegetables, cuts of meat… these things are supposed to decay, right? As Nicola Twilley writes, “What kind of unnatural technology could deliver a two-year old chicken carcass that still looked as though it was slaughtered yesterday?”But just a few decades later, Americans have done a full one-eighty. Livestock can be slaughtered thousands of miles away, and taste just as good (or better) by the time it hits your plate. Apples can be stored for over a year without any noticeable change. A network called the “cold-chain” criss-crosses the country, and at home our refrigerators are fooling us into thinking we waste less food than we actually do. Today, refrigeration has reshaped what we eat, how we cook it, and even warped our very definition of what is and isn’t “fresh.” Featuring Nicola Twilley.

  • For more than two hundred years Americans have tried to tame the Mississippi River. And, for that entire time, the river has fought back. Journalist and author Boyce Upholt has spent dozens of nights camping along the Lower Mississippi and knows the river for what it is: both a water-moving machine and a supremely wild place. His recent book, “The Great River: The Making and Unmaking of the Mississippi River” tells the story of how engineers have made the Mississippi into one of the most engineered waterways in the world, and in turn have transformed it into a bit of a cyborg — half mechanical, half natural. In this episode, host Nate Hegyi and Upholt take us from the flood ravaged town of Greenville, Mississippi, to the small office of a group of army engineers, in a tale of faulty science, big egos and a river that will ultimately do what it wants.

  • Helium is full of contradictions. It’s the second most abundant element in the universe, but is relatively rare on Earth. It’s non-reactive, totally inert—yet the most valuable helium isotope is sourced from thermonuclear warheads. And even though we treat it as a disposable gas, often for making funny voices and single-use party balloons, our global supply of helium will eventually run out. That’s because, at a rate of about 50 grams per second, this non-renewable resource is escaping the atmosphere for good. In this edition of The Element of Surprise, our occasional series about the hidden histories behind the periodic table’s most unassuming atoms, we examine the incredible properties and baffling economics of our most notable noble gas.

  • Jack Rodolico knows exactly what scares him. Sharks. But here’s what he doesn’t get: if he’s so freaked out, why can’t he stop incessantly watching online videos of bloody shark attacks? Why would he deliberately seek out the very thing that spooks him?To figure it out, Jack enlists the help of other scaredy-cats: our listeners, who shared their fears about nature with us. Together, Jack and the gang consider the spectrum of fear, from phobia to terror, and what it might mean when we don’t look away.Featuring Lauren Passell, Arash Javanbakht, Nile Carrethers, and Sushmitha Madaboosi.This episode originally aired in October 2022.

  • From the perspective of Western science, plants have long been considered unaware, passive life forms; essentially, rocks that happen to grow. But there’s something in the air in the world of plant science. New research suggests that plants are aware of the world around them to a far greater extent than previously understood. Plants may be able to sense acoustics, communicate with each other, and make choices… all this without a brain.These findings are fueling a debate, perhaps even a scientific revolution, which challenges our fundamental definitions of life, intelligence, and consciousness.Featuring Zoë Schlanger.

  • GPS is essential these days. We use it for everything – from a hunter figuring out where the heck they are in the backcountry, to a delivery truck finding a grocery store, to keeping clocks in sync.But our reliance on GPS may also be changing our brains. Old school navigation strengthens the hippocampus, and multiple studies suggest that our new reliance on satellite navigation may put us at higher risk for diseases like dementia. In this episode, we map out how GPS took over our world – from Sputnik’s doppler effect, to the airplane crash that led to its widespread adoption – and share everyday stories of getting lost and found again.

Here’s the peer-reviewed study, published in the journal Nature, that found that young people who relied on GPS for daily driving had poorer spatial memories.

  • Once again, it’s that wonderful time when scientists everywhere hold their breath as the team opens the Outside/Inbox to answer listener questions about the natural world. Today’s theme is smell: how it works in the nose, the mind, and how much is still unknown about the fifth sense.Question 1: Does it gross you out to know that every time you smell something, a little bit of that thing… is in your nose? What happens to the molecules we smell?Question 2: Why do smells have such a powerful connection to memory?Question 3: How do pheromones work in humans? Do ‘ideal mates’ really ‘smell better’ to us?Question 4: Why does the smell of florals sometimes precede a migraine?Question 5: What’s anosmia?Featuring Rachel Herz, Bob Datta, Katie Boetang, and Tristram Wyatt, with thanks to Stephanie Hunter.
